double needle quilting
I've been told that I can use a double needle for quilting. I believe this. But...when I use a double needle I get a zigzag on the bottom. I don't want that on the back of my quilt. I'm told I need to thread my machine differently and I will have a double row on top and a double row on the bottom but I wasn't told how. Anyone heard of this? Can someone tell me how to do this?
